<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm wondering about the variable naming. It's m_ so one would assume it's a member variable, but that looks more like a static variable.
So better make it static and use the s_ prefix</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You're right. It is no member variable. No idea why I chose that name.
It is a pointer to the actual UnlockApp object, so that the signalhandler can call its methods.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">thinking about it: you don't need the pointer at all. You have the qApp* static pointer which you can just static_cast to UnlockApp*</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If the screen locker is set to not require a password to unlock, it will not show the password input field even when the powermanagement settings suspend the system and are set to require a password after resume (when it was already running at that point).
This locks people out of their system.
This patch adds a signal handler for SIGUSR1 that switches the running greeter to immediateLock mode. The locker sends that signal to make sure the greeter shows the password input field when necessary.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Disable "Require password after" in the screen locker settings (the default), set it to start after 1 min. (for easier testing).
Enable "Suspend session after" and set it to 2 minutes. (set the action to "Suspend", "Hibernate", or "Lock Screen", doesn't matter)
Make sure "Lock screen on resume" is enabled in the powermanagements "Advanced Options" (it is by default).
After 1 minute the screen locker kicks in, and doesn't require a password.
After 2 minutes the session gets suspended, hibernated or locked, and requires a password to resume.
Without this patch no password dialog is shown, the user cannot resume the session by entering the password.
With this patch this works: there is a password input field, the session is unlocked when the user enters the password.
